MASTER-IAC robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in IAC Teide Observatory (Tenerife) was pointed to the
Swift Trigger 650221/IGR J00291+5934 (Barthelmy et al., GCN 18061) 30 sec
after notice time and 88 sec after trigger time at 2015-07-25 02:13:33 UT.
On our first (20s
exposure) coadd set we clearly see IGR J00291+5934 Optical Counterpart
with 17.40+-0.10 unfiltered MASTER instrumental magnitude. The limit is
18.1. We have 131 images in two tube up to 2015-07-25 05:43:08 UT.
